Jake@JHM’s 2008 B7 A4 2.0T Product Development/Build Thread

Hey Guys,

I would like to start this thread off by saying thanks for all of the support you guys have given us this far! I would also like to thank again those of you who come to us for all of your maintenance or replacement parts and those of you who already purchased our JHM Short Shifter, our JHM Lightweight Flywheel and Clutch Combo, and even our JHM 4:1 Center Diff Upgrade.

For those of you who have never heard of us or barely know who we are, check out our Audizine Tuner Spotlight Video! (I know there aren’t any B7 A4s in this video but trust me, we have our hands in them and products are being developed!)


I purchased the car completely bone stock with the intent of having products developed and tested on it (Yes that means intentionally beating the crap out of my car to insure the quality of our parts). Those of you who came out to our annual BBQ in April may remember the car (Some of you felt the Trio Package).

Vehicle Specs:

2008 Audi A4 2.0T S-line quattro
6 –Speed Manual Transmission
96,000 Miles
100% Bone Stock (When I Got it)

The Car:



Our goal for the B7 A4 2.0T platform is to produce the quickest and fastest cars and to supply you with aftermarket support to get you there. We have completed these goals with every platform we have stepped into and will continue to do so. (See my sig for record setting videos)

Supplying tons of maintenance and replacement products is something we also do. We want to help keep our customers cars in tip-top shape and at the same time, keeping everything affordable. If there is something you are looking for on our website and do not see it, please let us know because we can get it for you.

JHM parts that are installed:

  1. JHM Solid Trio Package
  2. JHM Solid Cross-rod Upgrade
  3. JHM Stage 1 Lightweight Flywheel and Clutch Combo
  4. JHM 4:1 Center Diff Upgrade
  5. JHM Boost Gauge w/Podi Gauge Pod

JHM parts that we are currently developing:

  1. JHM Test-pipe/Downpipe
  2. JHM B7 A4 2.0T ECU Tune
  3. More to come!

I am VERY excited about this 2.0T build because we feel this platform has a lot of potential. I am also excited about being able to offer these products, even though we don’t have any “Power Adders” available for the public yet. However, soon enough we will have a complete product line.

Here are some install pics!

Here is a picture that can help answer a lot of questions we get about the JHM Stabilizer Bushing. As you can see the thicker delrin piece goes on the top and the thinner delrin piece goes on the bottom [up].

One of the most common questions we get is how much flywheel “chatter” you get when upgrading to our JHM Lightweight Flywheel and Clutch Combo for the B7 A4 2.0T. Because we get this question so often, I have put together a cabin noise video with the JHM Lightweight Flywheel and Clutch Combo installed with it completely silent inside of my car (windows up, AC and radio off) so you can get an idea on how little noise the lightweight flywheel actually makes.



Like I state in the video, it takes having to purposely shift into a high gear at a low speed to really bog the engine to make the lightweight flywheel make any kind of intolerable sounds. However, you will experience very similar results when bogging your engine with an OEM heavy dual-mass flywheel as well. Those of you who have a Test-pipe or some sort of aftermarket exhaust (completely stock exhaust in this video) will more than likely never hear it and if you have your windows down, AC/Heater on, or even your radio at moderate levels you will most likely not notice it either.

For those of you that are local, I would be more than happy to take you for a ride to hear it first hand!

If you have any questions, please ask! I am here to help.


2.0 is kinda a cool car. Nice post. The flywheel chstter is a good idea to show people that dont know juat now small of a issie it is…

Thanks! I am loving the car so far. Customers have always been a little nervous when it comes to flywheel “chatter” when in reality it is not very noticeable.

Congratulations on picking up the A4!

That is the best year because most all of the problem parts were sorted out. I look forward to seeing how that car responds to the full on JHM treatment.

Thanks! Yea as far as I know from all of the service records that I received when I purchased the car, the notorious cam follower has not be replaced. After 96k miles, I cannot wait to see what it looks like. :stuck_out_tongue:

The later model B7 A4s supposedly have been updated to prevent the cam follower failures, but from the research I have done it is still happening.

I will definitely keep every up to date when I take my HPFP apart.


Well Audi extended the warranty on most of the things that fail on the 2.0T FSIs (cam follower/intake cam/hpfp, PCV valve, intake manifold flap motor, and low side fuel pressure sensor) to 120K miles or ten years so if it fails before you guys go too crazy then the local dealership should replace it for free. Also in about 9K miles it is due for a timing belt replacement.

I can’t wait to see a K04 or JHM RS6-R on there.

Since my car came “updated” from the factory, I do not qualify for the warranty. It is for the 05.5, 2006, and some of the early 07s that get that treatment. An easy way for people to tell if their car has the updated parts from the factory is the color of the valve cover. The ones that came with silver are non updated and the ones with the black are the “updated”.

I right there with you! I can’t wait for some JHM Bigger Turbo action! ;D

Thats good information.

I don’t know too much on the 2.0. It seems the ko4 turbos bave not been a real big success. It would be interesting to see what jhm brings. Considering the rs6 has twin turbos and a 2x 2.1 motor the rs6r might be a good fit.

Jake that valve cover thing is crazy interesting do you have pictures for refrence and whats the d8fference in the valve covers on the update

At one point I had both silver and black valve covers in my hand (I picked up a spare valve cover and painted it, so I went from black to a painted silver) and the only noticeable difference is the color. All of the fittings are exactly the same and the PCV system connects right up with zero issues.

The RS6-R does sound to be a solid option as an upgrade. However, we will be crossing that bridge further down the road.

K04 does pretty well on the 2.0T (350hp crank) not like it is on the 1.8T (useless lol)

Wonder how much of a difference it would be to tune my 2.0t :stuck_out_tongue:

I thought the valve covers were updated because they would separate on the bottom and suck oil into the PCV valve. The glue wouldn’t hold. I never put two and two together with the updated parts since it seemed like those other parts failed all the time on all the 2.0Ts regardless of model year.

That is quite possible for the exact reason of the color change of the VC. I had just noticed that the cars that have the updated fuel pump components have the black valve cover as well.

Do it…get a jhm tune and then put audi rings on the vdub…wicked good

I was driving through the back roads this weekend and I decided to take a cell phone pic. [:D]



Very nice.
